CVE-2026-46902: Oracle ECC Framework Auth Bypass Flaw

CVE-2026-46902 Overview

CVE-2026-46902 is a critical vulnerability in the Oracle Enterprise Command Center Framework (ECC), a component of Oracle E-Business Suite. The flaw resides in the Core component and affects supported versions V15 and V16. An unauthenticated attacker with network access via HTTPS can exploit the issue without user interaction. Successful exploitation results in full takeover of the Oracle Enterprise Command Center Framework, compromising confidentiality, integrity, and availability. The weakness is categorized under [CWE-284] Improper Access Control.

Critical Impact
Remote, unauthenticated attackers can take over Oracle Enterprise Command Center Framework instances over the network, leading to complete loss of confidentiality, integrity, and availability.

Affected Products

Oracle Enterprise Command Center Framework V15
Oracle Enterprise Command Center Framework V16
Oracle E-Business Suite deployments using the ECC Framework Core component

Technical Details for CVE-2026-46902

Vulnerability Analysis

The vulnerability allows an unauthenticated remote attacker to compromise the Oracle Enterprise Command Center Framework over HTTPS. Oracle classifies the issue as easily exploitable, requiring no privileges and no user interaction. The attack targets the Core component, which mediates access to ECC dashboards, data sets, and configuration endpoints used by Oracle E-Business Suite modules.

Successful exploitation grants attackers full control over the ECC Framework. This exposes business-critical data presented through ECC dashboards and enables tampering with application state. The EPSS score is 0.483% with a percentile of 37.803 as of 2026-06-18, but the network-reachable nature of the bug and the lack of authentication elevate operational risk.

Root Cause

The issue is classified as Improper Access Control [CWE-284]. The Core component fails to properly enforce access restrictions on privileged operations, allowing unauthenticated callers to invoke functionality reserved for authenticated users. Oracle has not published implementation-level technical details in the Critical Patch Update advisory.

Attack Vector

The attack vector is network-based over HTTPS. An attacker reaches an exposed Oracle Enterprise Command Center Framework endpoint and submits crafted requests that bypass access control checks in the Core component. No credentials, prior foothold, or user interaction are required. Internet-exposed Oracle E-Business Suite deployments are at the highest risk.

No public proof-of-concept exploit, Exploit-DB entry, or CISA KEV listing exists for CVE-2026-46902 at the time of writing. Refer to the Oracle Security Advisory for vendor-supplied technical guidance.

Detection Methods for CVE-2026-46902

Indicators of Compromise

Unauthenticated HTTPS requests to Oracle Enterprise Command Center Framework endpoints originating from untrusted networks.
Unexpected administrative actions or configuration changes within ECC dashboards without a corresponding authenticated session.
New or modified ECC data sets, users, or scheduled jobs that do not map to authorized change tickets.
Outbound connections from Oracle E-Business Suite hosts to unfamiliar external IP addresses following ECC activity.

Detection Strategies

Monitor web server and reverse proxy logs for high volumes of HTTPS requests to ECC URIs from single source addresses.
Correlate ECC application logs with authentication events to identify privileged operations executed without a valid session.
Hunt for anomalous process execution or file writes on Oracle E-Business Suite application tier hosts.
Apply MITRE ATT&CK mappings for Initial Access (T1190 Exploit Public-Facing Application) on Oracle middleware assets.

Monitoring Recommendations

Centralize Oracle E-Business Suite, ECC, and WebLogic logs in a SIEM with retention sufficient for incident reconstruction.
Alert on changes to ECC role assignments, data set definitions, and integration configurations.
Track outbound network connections from Oracle middleware hosts and flag deviations from baseline.
Review CPU, memory, and request-rate baselines on ECC servers to catch abuse patterns.

How to Mitigate CVE-2026-46902

Immediate Actions Required

Apply the June 2026 Oracle Critical Patch Update for Oracle E-Business Suite to ECC Framework V15 and V16 without delay.
Inventory all Oracle Enterprise Command Center Framework instances, including non-production environments, and confirm patch status.
Restrict network access to ECC endpoints so that only trusted internal networks and authorized administrators can reach them.
Review ECC and E-Business Suite audit logs for signs of unauthorized access prior to patching.

Patch Information

Oracle addressed CVE-2026-46902 in the June 2026 Critical Patch Update. Patch details, prerequisites, and version-specific instructions are available in the Oracle Security Advisory. Administrators should follow Oracle's documented patch order for E-Business Suite components to avoid breaking dependent modules.

Workarounds

Place Oracle Enterprise Command Center Framework behind a VPN or zero-trust gateway to remove direct internet exposure.
Enforce IP allow-listing on reverse proxies and web application firewalls in front of ECC endpoints.
Disable or remove unused ECC dashboards and data sets to reduce the attack surface until patches are applied.
Increase logging verbosity on ECC and the underlying application server to support detection during the patch window.

bash

# Example: restrict ECC endpoint access at the reverse proxy (nginx)
location /ecc/ {
    allow 10.0.0.0/8;        # internal admin network
    allow 192.168.10.0/24;   # jump host subnet
    deny  all;
    proxy_pass https://ebs-app-tier.internal;
    proxy_set_header X-Forwarded-For $remote_addr;
